Prior to the invention of electricity in Sri Lanka, people widely used a Lampuwa to light their houses. A long rolled cotton cloth is inserted in the Lampuwa and fed by Kerosene oil. The flame of Lampuwa is extinguished when the Kerosene is over. A Lampuwa provides sufficient light to a room. Village people engage in their work during the night and at the dawn with the light emanated from the Lampuwa. Cooking and reading of books can well be done with the light of a Lampuwa.
